Civil Engineering Association

Dear members,

I have a device like the one in the picture attached.
LMSR-vk is able to perform the following DCP methods:
1. DPL (dynamic probing light) 10 kg / 50 cm
2. DPM (dynamic probing medium) 30 kg / 50 cm
3. DPH (dynamic probing heavy) 50 kg / 50 cm
4. DPSH-A (dynamic probing super heavy) 63,5 kg / 50 cm.
5. DPSH-B (dynamic probing super heavy) 63,5 kg / 75 cm.
Curently i am using the DPSH-B with readings of N at every 20cm (N20)

I am interesting in using the program NOVOSPT. For that i have to convert the N20 in N60 . Can anyoane help me in this problem? A book or a code will be very appreciated.

thank you in advance

Hi.

From my experience, the correlation between DPSH tests and SPT depends largely on the local conditions, so what we usually do is the following:
- establish a preliminary geotechnical investigation programme with a couple of SPT's and DPSH's in the same locations;
- establish correlations between DPSH and SPT with sufficient reliability;
- use the DPSH to refine the mesh of the site investigation.

Hope it helped.
Best regards.
